Solar led street light(CLASSIC) consists of the following components: solar panels, batteries, solar-powered controllers, illuminators and lights. It is an automatic control working system. The solar LED street light will automatically run when the system is set to work mode. The solar street light is the ideal road lighting. With the improvement of people’s living standards and the development of society, it will be the widely used sun. At night, the earth is provided with light for human illumination.

Solar LED street light uses solar panels to convert solar radiation into electricity during the day, and then store the batteries in the battery through intelligent controllers. When the night falls, the sun’s light intensity gradually decreases. When the intelligent controller detects that the light is reduced to a certain value, the battery is controlled to supply power to the light source, so the light will automatically turn on when it is dark. The intelligent controller is used to control the charge and discharge of the battery, as well as the opening and illumination time of the light source.

Ultrasonic welding is one of the most popular welding techniques used in the welding industry. It is fast, economical, and automated, and well suited for mass production, with production rates up to 60 parts per minute being possible. Ultrasonic welding uses ultrasonic energy at The high frequency (20–40 kHz) to produce low amplitude (1–25 μm) mechanical vibrations. The vibrations generate heat at the joint interface of the parts being welded, resulting in melting of the thermoplastic materials and weld formation after cooling. In addition to welding, ultrasonic energy is commonly used for processes such as inserting metal parts into plastic or reforming thermoplastic parts to mechanically fasten components made from dissimilar materials. Ultrasonic Welding is used in almost all major industries like automotive, electronic and appliances, medical, packaging etc. A lim In the case of ultrasonic welding is that with current technology, large joints cannot be welded in a single operation. In addition, specifically designed joint details are required. Ultrasonic vibrations can also damage electrical components, although the use of higher frequency equipment can reduce this damage. Also, depending on the parts to be welded, tooling costs for fixtures can be high.
Sewn seam is usually the most critical position for the permeability of the material, but not in case of strength, so its use is indispensable where seam tightness is not a requirement. Seam rigidity, especially in folded places, results in weakening the joint and it Is important where possible to avoid it in folds. Special prominence is given to the essential properties of multi-layer fabrics with woven fabric as a basic component for use in tarpaulins, tents, awnings, sailboats, aircraft, materials for protective clothing, etc. Basic properties of materials with limited values ​​are emphasized, and an experimental study of some selected materials is given.
Developments in fabric joining for smart clothing
New technologies and methods being used in the garment manufacturing include bonding and welding. Bonding uses an adhesive and the two types of welding are ultrasonic and laser. The traditional method of sewing is already added too by these new technologies, not supplanted. At these bonding methods and includes information about the components, machinery used, the physical join, the type of applications and the advantages and disadvantages of using each method.For more information click on XingHui Welding Parts Suppliers

If you live in a city and walk alone at night, you may prefer a well-lit route. Even if you live in a more suburban area, this certainly applies. Linking public lighting(CLASSIC) to safety is one of the common feelings that I can almost resonate with everyone.

After installing 3,500 new public lights in London’s Wandsworth borough in the mid-1980s as part of its overall crime reduction program, researchers at the University of Southampton decided to compare the crimes reported before and after the upgrade. Although the increased lighting for decades has become a major component of urban crime prevention, the researchers found „there is no evidence to support the hypothesis of improving street lighting to reduce reporting crime.“

American cities tried similar experiments during the same period, and the results were mixed. According to a systematic review of urban lighting experiments in the United States in 2007, the increase in public lighting in Indianapolis, Harrisburg, New Orleans, and Portland, Oregon is inconsistent with the decline in crime rates in affected areas, but in Milwaukee, Atlanta. This is true. , Kansas City and Fort Worth. However, even in American cities where public lighting is “effective,” they seem to be inconsistent: although Fort Worth sees a reduction in all types of crime, Kansas City has only reduced violent crime.

But criminologist Ken Pease says things here really make you in trouble: public lighting makes criminals as much as their potential victims. As public lighting increases, potential thieves can more easily see the contents of parked cars, do not need to carry a flashlight (which can warn someone of their existence), and can take up a place and determine if anyone around them can stop them Run-in. Light may scare off criminals, but it can also tell them enough houses, streets or parking lots to find out if they have anything terrible.

So what happens when you take public lighting? A recent study conducted in Chicago on behalf of the Chicago Department of Transportation found that street power outages have different effects on different neighborhoods. “For some communities, there are not enough crimes in areas affected by blackouts to estimate models,” the authors said. At the same time, when public lighting in other communities went out, the crime rate rose by 134%. Efforts to reduce light pollution (rather than blackouts) have been carried out in the United States and Europe, and there has been no corresponding increase in crime; in addition to the possible energy-saving lighting regulations passed in Auckland in 2002, the murders in 2011 have been accused of soaring.

The connection between light and crime may not be what most of us think, but the connection between light and our sense of security is exactly what it has always been. Southampton researchers who measured the crime rate at Wandsworth also found that the new public lighting „provides a guarantee for those who are afraid of using public space,“ especially women. Lighting adds community awareness and community pride. It brings us to the outdoor community and helps us understand each other. Fear keeps us away from the alley, the attraction of light and what it represents leads us to the illuminated streets.

Right cleaning methods of Hot Air Stenter play an important role in smooth operation, otherwise, it will affect service life of machines.

All the printing and dyeing company wants to make full use of stenters and maintain high evaporation efficiency. Once the equipment is put into use, it’s the manufacturer’s own business.

One of the defects of common stenters is the decrease of efficiency caused by the clogging of the cotton dust filter. During each operation, the cotton dust and other impurities filtered out from the circulating air system of drys gradually accumulate, generate resistance, reduce the pressure of the air vent, and thus decrease the evaporation efficiency.

At present, many dryers and heat treatment equipment are still using a plug-in filter. If they do not open the door of the drying room, the machines cannot be cleaned. Because the cleaning of the filter and the re-heating of the drying room will waste time, it will have a bad impact on the production efficiency of the equipment.

The double-filter system introduced in the data about 6 years ago is a big step forward. This device is installed outside of the machine and can be taken out without opening the drying room door. It can be cleaned without stopping the machine. When the filter is pulled out, the other filter automatically replenishes the position. The pressure still decreases due to the accumulation of cotton flock, which means the efficiency will also be reduced.

Printing manufacturers understand that although cotton flock is removed and a basic cleaning is carried out on each shift, the filter screen will gradually become clogged and therefore require frequent thorough cleaning. Above all, the filter screen must be removed and cleaned with detergent by a high-pressure cleaning device.

LiCheng company is a recognized global leaders in hot air stenter machine and Flat Screen Printing Machine manufacturing, who is famous for advanced technology and superior quality.

The street lights of Led street lights Manufacturers(CLASSIC) are different from traditional high-pressure sodium lamps. High-power LED street light adopts low-voltage DC power supply. It uses Gan Power blue led and yellow phosphor to synthesize high-performance white light-emitting diode. It has the characteristics of high efficiency, safety, energy saving, environmental protection, long life, fast response and unique color index. Can be widely used in urban road lighting. The outer casing can be made of PC tube, with a high temperature of 135 degrees and a low temperature of 45 degrees.

A light-emitting diode (abbreviated as LED) is a highly efficient solid-state light source that emits weak power based on a semiconductor PN junction. In a certain positive bias and injection current, the holes injected into the P region and the electrons injected into the N region emit photons after being diffused into the active region by radiation, and the radiation directly converts the energy into light energy.

2. LED street light has two unique optical designs, which will illuminate the led street light to the required lighting area to further improve the lighting efficiency to achieve energy saving.

3. The efficiency of LED light source has reached 110-130lm / w, and there is a lot of room for development, the theoretical value is 250lm / w. The luminous efficiency of the high-pressure sodium lamp increases with the increase of power. Therefore, the overall luminous efficiency of the LED street lamp is higher than that of the high-pressure sodium lamp; (this overall luminous effect theoretically, the light efficiency of the high-pressure sodium lamp exceeding 250 W is actually higher than that of the LED).

4. The color of the LED street light is much higher than that of the high-pressure sodium lamp. The color index of the high-pressure sodium lamp is only about 23, and from the street color index to 75 or more, from the visual psychological point of view, to achieve the same brightness, the LED street lamp illumination can be higher than the high-pressure sodium lamp. The average is 20% lower (refer to the UK Lighting Standards Principle).

5. Light decay is small, the light decay is less than 3% in one year. It still meets the road use requirements after 10 years of use, while the high-pressure sodium lamp has decreased by more than 30% in one year. Therefore, the use of LED street lamps in power supply design can be lower than that of high-pressure sodium lamps.

Australia is a developed country in the southern hemisphere, with a GDP ranking 12th in the world and a population of about 23,000,000. Therefore, its manpower manufacturing industry is not so strong, resulting in lighting manufacturing conditions similar to the few local lighting companies. As a result, Australia’s Led Public lighting(CLASSIC) products rely heavily on imports, most of which are from China.

In this beautiful and expansive country, home to 7m-8m families, average family own 70-80 fixtures, most of which are about MR16 halide lamps and traditional high-pressure sodium lamps. This huge country has great potential. Australia is the first country to completely eliminate traditional incandescent lamps, a paradise for efficient lighting products.

In 2015, China’s total exports of lighting products to Australia reached US$71.4 million, an increase of 14.20% over the previous year, including US$39.6 million, an increase to 13.08%, and ranked 10th among exporting countries.

With the development and improvement of the LED industry and the improvement of green awareness, the high price of LED and the volume of traditional products have dropped significantly. Therefore, since 2010, LED public lighting products have continued to grow locally.
